BENJAMIN F. WILSON, OF HASTINGS, NEBRASKA.

SHOCY-LOADER.

Application filed March 20, 1908.

To all whom it may concern:

Be it known that I, BENJAMIN F. \VILsoN, a citizen of the United States,residing at Hastings, in the county of Adams and State of Nebraska, haveinvented certain new and useful Improvements in Shock-Loaders; and I dohereby declare the following to be a full, clear, and exact descriptionof the in vention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to shock loaders.

The object of the invention is to provide a device by means of whichshocks of hay or grain may be loaded directly onto a wagon withoutstopping the latter.

A further object is to provide means whereby the shocks may be raised byapparatus under the control of the driver who will not be required toleave his seat on the wagon during any part of the operation.

A still further object is to provide means for automatically returningthe fork or carrier to its operative position after it has discharged ashock upon the wagon.

IVith these and other objects in view the invention consists in mountingupon a wagon body a suitable upright and in pivtally mounting at a pointnear the base of said upright two swinging arms, one of which isprovided with a pulley and the other of which carries a pivoted carrierfor raising the shocks and discharging them upon the wagon.

The invention consists further in providing means for raising the twopivoted arms above mentioned and for automatically tilting the carrier.

In the accompanying drawings: Figure 1 is an elevation showing myimproved shock loader in operative position. Fig. 2 is a top plan View.

In carrying out my invention I affix an upright 1 in any suitable mannerto one of the portions 2 of the framework of the wagon or hay rack, andpivotally secure arms 3 and 4 to a bracket 5 mounted on the lowerportion of the upright 1. The wheels of the wagon or rack are indicatedby the numerals 6 and 7, these wheels communieating motion to thesprocket wheels 8 and 9 which serve to drive the mechanism for raisingthe carrier. Sprocket wheels 10 and 11 are driven by means of chains 12and 13 carried by the sprocket wheels 8 and 9, these wheels 10 and 11being slidably mounted Specification of Letters Patent. 3 Patented Sept.21, 1909.

and normally pressed inward by means of coiled springs 14 and 15.Connected with the sprocket wheels 10 and 11 are toothed collars 16 and17 loosely carried by a main shaft 18 on which latter are mounted fixedcollars 19 and 20 also provided with teeth for engaging the teeth of thecollars previously mentioned. sprocket wheel 21 driving a chain 22 whichin turn engages the sprocket wheel 23 carried by short shaft 24;designed to drive the pulley 25.

A pulley 25 is mounted in a recess 26 in the upper end of member 1, anda similar pulley 26 is mounted in. a recess in the arm 3. A chain 27 isconnected with the pulley 25, passes over pulley 25*, thence over pulley26, and is connected with the carrier 28, at its pivotal point. A brace29 is secured to the cross bar 30 of the carrier and connected with suchbrace 29 is a chain 31 provided with a ring 32 sliding on the brace.Chain 31 also connects with chain 27 at the point 33 between the uprightand arm 3 when the latter is in its lowered position as shown in Fig. 1.A short chain 3% connects the chain 27 with the right-hand side of thecarrier at 35, and a connecting device 36 is secured at 37 to theopposite side of the carrier and to the arm I at the point 38. A shortchain 39 connects arms 3 and 4 near their inner ends to prevent themfrom spreading beyond a given extent, and a chain 56 connects arm 3 andupright 1.

Mounted upon the upright 1 is a spring 40 with which arm 3 is designedto contact when it is raised to a nearly vertical position, and toassist in returning the arm to its lowered position when the chain 27 isfreed in the manner hereafter described. A shaft 24 is mounted in boxes41 and 4:2, and to one of these boxes is pivotally secured a member 43designed to act as a brake upon pulley 25, this brake being operated bymeans of a rod 44; connected with brake member 43 by chain 45. A clutch46 causes sprocket wheel 23 to drive shaft 24:, such clutch beingoperated by means of a lever 47 pivoted at 48. A rod 49 connects withthe lever 47 and is operated aut01natically by a device 50 on the arm 3when the latter is brought to the proper position for the dumping of thecarrier. Lever 4:7 is also connected with an arm 51 which is under thecontrol of the driver and may be operated by him when desired.

Shaft 18 carries a.

The several parts being in the position shown in Fig. l, a shock of hayor grain is caught upon the carrier and the clutch is thrown intooperative position by the driver, the pulley 25 being thereby set inmotion for the purpose of winding the chains 27 and 31. As the arm 4 israised to a given height, it is brought into contact with arm 3 and thetwo arms are then raised together into an approximately verticalposition. During this movement the chain 36 at the inner end of thecarrier first becomes slack and later as the arms approach their vertical position this chain'becomes taut. The carrier is pivoted at thepoint 52 and is braced at its outer end by the chain 34 as previouslystated. When the chain 36 connecting the carrier with arm 4 becomestaut, the carrier will tilt slightly and the ring 32 will slide on thebrace 29 toward the pivot 52. As the arms are further raised, thecarrier is dumped, discharging its load upon the wagon. At this stage ofthe operation the disengaging device 50 comes in contact with arm 49throwing the clutch out and releasing the chain wound upon pulley 25.The spring 40 then causes the arms to be thrown outward in order thatthey may return to the position shown in Fig. 1.

Arm 55 is secured to the body of the wagon or hay rack (the location ofwhich is indicated by the dotted line), is attached to the carrier,'andserves to guide the latter while it is being raised and lowered.

What I claim as new and desire to secure by Letters Patent, is

1. In a shock loader, in combination, a vehicle for receiving theshocks, an arm connected with the vehicle and arranged to swingvertically, a carrier at the end of the arm, a chain for swinging thearm, means connected with said arm and with the carrier for tipping thecarrier when the arm is swung to a predetermined position, and chainsconnected with the chain first mentioned and with the carrieron eachside of its pivotal point for holding the carrier in its normal positionwhen lowered.

2. In a shock loader, a vehicle for receiving the shocks, an uprightsecured thereto, a plurality of arms pivoted at the base of the upright,a pulley at the end of the upright, a pulley mounted at the end of oneof the arms, a carrier pivoted to the end of the remaining arm, a chainconnected with the carrier near its pivotal point, said chain passingover each of said pulleys, means for winding the opposite end of thechain, a second chain connected with the chain first mentionedapproximately midway of its length and with the carrier at one side ofits pivotal point, a third chainconnected with the chain first mentionedand with the carrier on the other side of its pivotal point, and meansconnected with the arm lastmentioned for preventing one end of thecarrier from assuming an elevation equal to that of the opposite endwhen the arms have been brought to their highest point.

3. In a shock loader, a vehicle for receiving the shocks, an uprightsecured thereto,

a plurality of arms pivoted at the base of the upright, a pulley mountedat the end of the upright, a second pulley at the outer end of one ofthe arms, a carrier pivoted to the end of the remaining arm, a chainconnected with the carrier near its pivotal point, said chain passingover each of said pulleys, means for winding the opposite end of thechain, a second chain connected with the chain first mentionedapproximately midway of its length and with the carrier at one side ofits pivotal point, a third chain connected with the chain firstmentioned and with the carrier on the other side of its pivotal point,and means connected with the arm last mentioned for preventing one endof the carrier from assuming an elevation equal to that of the oppositeend when the arms have been brought to their highest point, means forautomatically disconnecting the winding mechanism, and a spring forcausing the arms to return to their lowered position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
